Abstract: Techniques are disclosed for efficient computation of consecutive values of one-way chains and other one-way graphs in cryptographic applications. The one-way chain or graph may be a chain of length s having positions v i=1, 2, ...s each having a corresponding value vi associated therewith, wherein the value vi is given by vi=h(vi+1), for a given hash function or other one-way function h. An initial distribution of helper values may be stored for the one-way chain of length s, e.g., at positions given by i=2j for 0 j log2 s. A given one of the output values vi at a current position in the one-way chain may be computed utilizing a first helper value previously stored for another position in the one-way chain between the current position and an endpoint of the chain. After computation of the given output value, the positions of the helper values are adjusted so as to facilitate computation of subsequent output values. Advantageously, a storage-computation product associated with generation of the output values of the one-way chain has a complexity O((logs)2).

Title: High profile geotextile fabrics
Inventor: THEISEN MARC S
IPC: E02D3/12
Filed: 1994-09-15
Granted: 2010-01-12
Abstract: A method for stabilizing soil and reinforcing vegetation includes placing a single-layered, three-dimensional, high-profile woven geotextile fabric (10) into the soil. The single-layered, homogeneous fabric (10) is woven from monofilament yarns (12, 14) having different heat shrinkage characteristics such that, when heated, the fabric forms a thick three-dimensional, cuspated profile. The monofilament yarns (12, 14) have a relatively high tensile strength and a relatively high modulus at 10 percent elongation so as to provide a fabric which is greater in strength and more dimensionally stable than other geotextile structures. Thus, the geotextile fabric (10) is suitable for use on slopes, ditches and other embankments and surfaces where erosion control, soil stabilization and/or vegetative reinforcement may be necessary. The homogeneous, single- component nature of the fabric (10) promotes easier handling and minimizes failure points, while offering a thick, strong and dimensionally stable product upon installation.

Granted: 2012-11-27
Abstract: A casing brush assembly (1) comprises a mandrel (2), upper and lower stabilisers (5,6), a brash (9) and a magnet assembly (10). The magnet assembly comprises a plurality of helically extending brush elements each of which is spaced from the underlying mandrel so that it can flex inwardly to accommodate variations in casing diameter. The thickness of the brush elements is relatively thin in the portions which connect the central regions to the ends of the brush with the result that the deflection of the brush elements is largely accommodated by the relatively thin regions. The magnet assembly (10) includes three rings of magnets held in a non- magnetic cage and located beneath a thin cover of non-magnetic material. The assembly can be used in a non-rotating mode (in which the brush is free to rotate relative to the mandrel) or in a rotating mode in which the brush is rotationally fast with the mandrel.
